No one "signs" to the contest, there's a function of Flickr groups that must be read and clicked-through before joining the group and submitting images, although it's clear that nobody actually does this, and there is no way to "sign" anything. On top of that, Flickr already gives a specific set of licenses: None, Public Domain, CC-BY v2, CC-BY-NC v2, CC-BY-SA v2, and CC-BY-NC-SA v2.
The only way we could distribute the images under a different license is if the authors stated the license in the description or something. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to ubuntu-wallpapers in Ubuntu. https://bugs.launchpad.net/bugs/1595017 Title: u-wallpapers include Creative Commons v2 licenses which are controversial Status in ubuntu-wallpapers package in Ubuntu: Confirmed Bug description: The Ubuntu Wallpapers for 15.10 include Creative Commons version 2 licensed photos. https://bazaar.launchpad.net/~ubuntu-art-pkg/ubuntu- wallpapers/ubuntu/revision/166 This is in contrast to what was in debian/copyright up until that point and what I believe the guidelines say: https://wiki.ubuntu.com/Artwork/Documentation/Backgrounds There's good reason to have version 3 of Creative Commons by the minimum standard. It is widely believe in Debian that version 2 isn't good enough. (Version 1 is definitively believed to have not been DFSG-compatible). See https://wiki.debian.org/DFSGLicenses #Creative_Commons_Attribution_Share-Alike_.28CC-BY-SA.29_v4.0 And see bug 1588938 as just one example, where Debian developers reported the issue with CC version 2 files to the GNOME developers who replaced the images in the new release. To summarize, Creative Commons version 2 licenses should be avoided in Ubuntu because they are mostly avoided in Debian.
